Traumatic Stress Among Women who are Incarcerated: A Community Engaged Approach to Determining Needs and Opportunities for Intervention.

The rate of increase at which women are incarcerated in the United States dramatically outpaces the rate of increase among men. Women frequently enter incarceration after facing extensive trauma and often suffer the consequences of unacknowledged and undertreated post-traumatic stress disorder (PTSD). Yet, little is known regarding the types of traumas that women who are incarcerated (WI) experience, the types/magnitude of traumatic stress symptoms endured, or attitudes towards intervention.

Sustainable practice in gastroenterology: travel-related CO emissions for gastroenterology clinic appointments in Canada.

Background: Telemedicine is increasingly common in gastroenterology and may represent an opportunity for improving sustainability in medical care. The purpose of this study was to determine the carbon emissions related to travel for in-person gastroenterology clinic appointments.

Methods: We conducted a cross-sectional analysis evaluating carbon emissions associated with travel to gastroenterology appointments over a 2-week period.

Environmental exposures and the risk of hepatocellular carcinoma.

The global epidemiology of HCC is shifting due to changes in both established and emerging risk factors. This transformation is marked by an emerging prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes, alongside traditional risks such as viral hepatitis (HBV and HCV), and exposure to chemical agents like aflatoxin, alcohol, tobacco, and air pollution. This review examines how environmental exposures and evolving liver pathology, exacerbated by lifestyle and metabolic conditions, are contributing to the rising worldwide incidence of HCC.

Intention-to-treat outcomes of patients with hepatocellular carcinoma receiving immunotherapy before liver transplant: The multicenter VITALITY study.

Background & Aims: The use of immune checkpoint inhibitors (ICIs) in patients with advanced hepatocellular carcinoma (HCC) has become widespread with encouraging outcomes in the neoadjuvant setting. Safety and intention-to-treat (ITT) outcomes in the peri-transplant setting are currently based on small and heterogenous single-center reports.

Methods: This first multiregional US study (2016-2023) included 117 consecutive patients with HCC assessed for liver transplantation (LT) and treated preoperatively with ICIs.

Development and Validation of a Noninvasive Model for the Detection of High-Risk Varices in Patients With Unresectable Hepatocellular Carcinoma.

Background & Aims: Noninvasive variceal risk stratification systems have not been validated in patients with hepatocellular carcinoma (HCC), which presents logistical barriers for patients in the setting of systemic HCC therapy. We aimed to develop and validate a noninvasive algorithm for the prediction of varices in patients with unresectable HCC.

Methods: We performed a retrospective cohort study in 21 centers in the United States including adult patients with unresectable HCC and Child-Pugh A5-B7 cirrhosis diagnosed between 2007 and 2019.

A bioprinted sea-and-island multicellular model for dissecting human pancreatic tumor-stroma reciprocity and adaptive metabolism.

Pancreatic ductal adenocarcinoma (PDAC) presents a formidable clinical challenge due to its intricate microenvironment characterized by desmoplasia and complex tumor-stroma interactions. Conventional models hinder studying cellular crosstalk for therapeutic development. To recapitulate key features of PDAC masses, this study creates a novel sea-and-island PDAC tumor construct (s&i PTC).

Screening for exclusion of high-risk bleeding features of esophageal varices in cirrhosis through CT and MRI.

Background & Aim: Esophageal varices (EV) screening guidelines have evolved with improved risk stratification to avoid unnecessary esophagogastroduodenoscopy (EGD) in individuals with low bleeding risks. However, uncertainties persist in the recommendations for certain patient groups, particularly those with hepatocellular carcinoma (HCC) and/or receiving non-selective beta-blockers (NSBB) without prior endoscopy. This study assessed the efficacy of imaging in ruling out EVs and their high-risk features associated with bleeding in patients with cirrhosis and with HCC.

Social media consumption and depressive symptoms during the COVID-19 lockdown: the mediating effect of physical activity.

Introduction: Social media platforms played a critical role during the COVID-19 pandemic. This study aimed to explore: (1) the changes in social media consumption patterns, physical activity levels/sedentary behavior, and depressive symptoms, and (2) how the changes in social media consumption patterns predict the changes in depressive symptoms while investigating the mediating role of changes in physical activity levels/sedentary behavior between before, and after the COVID-19 lockdown among U.S.

Novel urine cell-free DNA methylation markers for hepatocellular carcinoma.

An optimized hepatocellular carcinoma (HCC)-targeted methylation next generation sequencing assay was developed to discover HCC-associated methylation markers directly from urine for HCC screening. Urine cell-free DNA (ucfDNA) isolated from a discovery cohort of 31 non-HCC and 30 HCC was used for biomarker discovery, identifying 29 genes with differentially methylated regions (DMRs). Methylation-specific qPCR (MSqPCR) assays were developed to verify the selected DMRs corresponding to 8 genes (GRASP, CCND2, HOXA9, BMP4, VIM, EMX1, SFRP1, and ECE).

Impact of Cell-Debris and Room-Temperature Storage on Urine Circulating Tumor DNA from Hepatocellular Carcinoma.

This study evaluated the impact of cell debris and 7-day room temperature storage on the quality and yield of transrenal DNA. Archived urine specimens collected from five hepatocellular carcinoma (HCC) patients and two pregnant women carrying male fetuses were used to assess the impact of cell debris on urine cell-free DNA (ucfDNA) isolation as measured by quantitative PCR for Y-chromosome DNA, or HCC-associated mutation and methylation markers, and by capillary electrophoresis. Prospectively collected urine from 21 HCC patients was aliquoted after collection for paired immediate freezing versus 7-day room temperature storage followed by freezing for further analysis.

Perceived Constraints to Pickleball Participation Among Black Older Adults.

Pickleball offers sociopsychological and physical activity benefits for older adults but lacks racial diversity. The purpose of this study was to identify constraints to pickleball participation with Black older adults (65+ years) as well as examine differences based on physical activity and sex. A Qualtrics panel included Black older adults (N = 292) who have heard of pickleball and are physically able to play but have not played.

Single-molecule genome-wide mutation profiles of cell-free DNA for non-invasive detection of cancer.

Somatic mutations are a hallmark of tumorigenesis and may be useful for non-invasive diagnosis of cancer. We analyzed whole-genome sequencing data from 2,511 individuals in the Pan-Cancer Analysis of Whole Genomes (PCAWG) study as well as 489 individuals from four prospective cohorts and found distinct regional mutation type-specific frequencies in tissue and cell-free DNA from patients with cancer that were associated with replication timing and other chromatin features. A machine-learning model using genome-wide mutational profiles combined with other features and followed by CT imaging detected >90% of patients with lung cancer, including those with stage I and II disease.

"You Just Have to Keep It Movin':" Perceptions of Physical Function Limitations in an African American Health Ministry.

Physical function (PF) limitations are common in aging. However, there is a dearth of interventions focused on addressing PF limitations in community-based settings, particularly in minoritized communities. To guide intervention development, we conducted focus groups to understand perceptions of PF limitations, gauge intervention interest, and identify potential intervention strategies as part of a large health partnership of African American churches in Chicago, IL.

Genomics of plant speciation.

Studies of plants have been instrumental for revealing how new species originate. For several decades, botanical research has complemented and, in some cases, challenged concepts on speciation developed via the study of other organisms while also revealing additional ways in which species can form. Now, the ability to sequence genomes at an unprecedented pace and scale has allowed biologists to settle decades-long debates and tackle other emerging challenges in speciation research.

Changes in children's dental fear after restorative treatment under different sedation types: Associations with parents' experiences and dental health.

Background: Dentists often use sedative medications such as nitrous oxide inhaled sedation and general anesthesia (GA) to help decrease patient fear and manage paediatric patients' behavior during treatment.

Aim: The goal of this study was to examine factors associated with dental fear changes after restorative dental treatment under nitrous oxide or GA in children 4-12 years old.

Design: A prospective cohort study of 124 children examined changes in dental fear, number of treatment visits, and parental factors among children receiving restorative dental treatment under nitrous oxide (n = 68) or GA (n = 56) sedation.

Sport participation, acculturative stress, and depressive symptoms among international college students in the United States.

Introduction: The distinctive social nature of sport in its capacity to promote immigrants' adaptation to the new society has been regarded as a vehicle to cope with adverse mental health outcomes derived from acculturative stress (AS) and feelings of marginalization. However, the evidence on the relationship between sport participation (SP), AS, and mental health have been lacking and fragmented. Recognizing this challenge, we examined the mediating effect of AS on the relationship between SP and depressive symptoms (DS) among international college students in the USA.
